What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introduction and hypothesisThe International Consultation on Incontinence Questionnaire (ICIQ) Bladder Diary (BD) is a standardized and validated diary, developed in the English language, designed to assess lower urinary tract symptoms (LUTS) in men and women. This study reports the translation, cross-cultural adaptation and validation process of this diary to the Portuguese language.
methodsAfter translation and back-translation of the ICIQ-BD to Portuguese, 140 urologic patients were asked to fill in this 3-day diary as well as the Overactive Bladder questionnaire Short Form (OABqSF) and a questionnaire evaluating the difficulties in filling out the ICIQ-BD. A subset of 60 patients filled out a second diary with/without LUTS treatment in between (30 patients in each group). In addition, content validity, internal consistency, criterion and construct validity were tested.
resultsThe Portuguese version of the ICIQ-BD showed adequate internal consistency (Cronbach's alpha of 0.78), and patients reported few difficulties in filling out this tool, answering most commonly 1 on a 1-6 scale of difficulty. Excellent test-retest reliability and responsiveness of the diary were observed when comparing the first diary to a second completed 2-6 weeks later. Criterion validity was also confirmed, given the good correlation with the OABqSF (Pearson's 0.386-0.447). Finally, construct validity was established through statistically significant concordance between data obtained in the BD with generally accepted theories.
conclusionThe present version of the ICIQ-BD is the first bladder diary successfully validated in the Portuguese language. It is a suitable and standardized tool for scientific research and diagnostic assessment of LUTS in adult men and women.
